french onion and apple grilled cheese

French Onion and Apple Grilled Cheese…with crispy prosciutto and gouda cheese too. Giving the classic french onion grilled cheese an autumn twist and it is SO GOOD. Apple cider caramelized onions, layered between two slices of sourdough bread with crispy prosciutto, thinly sliced apples, creamy fontina, and sharp gouda cheese.
